Voyager 1 Spotted from Earth with radio antennas

[Artie Lekstutis]

Wikipedia has a fairly readable explanation of the 'Pioneer Anomaly', 
and some of the possible explanations:
     http://en.wikipedia.org/wiki/Pioneer_anomaly

Or the JPL report, if you don't mind shelling out some money, or can 
find a copy at your local university library:
     http://prd.aps.org/abstract/PRD/v65/i8/e082004

Sadly, it's probably nothing more exotic than 'asymmetric radiation of 
waste heat':

Dark matter theories are much more fun :-)
